摘要
本研究基于出口产品质量升级的视角，探讨“一带一路”倡议对中国贸易强国建设的促进作用。通过构建双重差分模型，利用2008—2015年中国海关数据与城市统计数据进行实证分析。研究发现，“一带一路”倡议显著提升了中国企业的出口产品质量，且该效应在非国有企业及第二产业中更为明显。异质性分析表明，地区发展水平、企业性质和产业类型是影响政策效果的重要因素。基于此，本文提出实施差异化区域支持政策、构建多层次创新体系及推动产业精准扶持等建议，以助力“一带一路”高质量发展与贸易强国建设。

Abstract
This study explores the Belt and Road Initiative's role in promoting China's transition into a trade power from the perspective of export product quality upgrading. Employing a Difference-in-Differences model and analyzing Chinese customs data and urban statistical data from 2008 to 2015, it reveals that the BRI significantly enhances Chinese firms' export product quality, with a more pronounced effect in non-state-owned enterprises, and the secondary sector. Heterogeneous analysis indicates that regional development levels, firm ownership, and industry types are key factors influencing the policy's effectiveness. Consequently, the study suggests implementing differential regional support policies, establishing a multi-level innovation system, and promoting targeted industrial support to boost high-quality BRI development and bolster China's journey to becoming a trade power.
Key words： Belt and Road Initiative; Export product quality; Trade power construction
